Publications

2d-3d reasoning and augmented reality publications December 1, 2012

Implementation of an Augmented Reality System for Training Dismounted Warfighters

Rakesh Kumar, Supun Samarasekera, Han-Pang Chiu

We describe the technical methods and experimental results on building an Augmented Reality Training system for training dismounts doing maneuver operations.

2d-3d reasoning and augmented reality publications November 1, 2012

Multi-Sensor Navigation Algorithm Using Monocular Camera, IMU and GPS for Large Scale Augmented Reality

Supun Samarasekera, Rakesh Kumar

Camera tracking system for augmented reality applications that can operate both indoors and outdoors is described. The system uses a monocular camera, a MEMS-type inertial measurement unit (IMU) with 3-axis gyroscopes and accelerometers, and GPS unit to accurately and robustly track the camera motion in 6 degrees of freedom (with correct scale) in arbitrary indoor or outdoor scenes.

2d-3d reasoning and augmented reality publications June 1, 2012

Magic Mirror: A Virtual Handbag Shopping System

Supun Samarasekera, Rakesh Kumar

We present an augmented reality system based on Kinect for on-line handbag shopping. The users can virtually try on different handbags on a TV screen at home.

2d-3d reasoning and augmented reality publications June 1, 2012

Stereo Vision Embedded System for Augmented Reality

Supun Samarasekera, Rakesh Kumar, Gooitzen van der Wal

Stereo Vision processing is a critical component of Augmented Reality systems that rely on the precise depth map of a scene to properly place computer generated objects with real life video.

Multi-modal data analytics publications June 1, 2011

Vehicle Tracking Across Nonoverlapping Cameras Using Joint Kinematic and Appearance Features

Bogdan Matei, Supun Samarasekera

We describe a vehicle tracking algorithm using input from a network of nonoverlapping cameras.

2d-3d reasoning and augmented reality publications June 1, 2011

High-Precision Localization Using Visual Landmarks Fused with Ranged Data

Han-Pang Chiu, Supun Samarasekera, Rakesh Kumar

In this paper, we demonstrated that with the use of precise 3D Li-dar range data, we are able to build a global consistent database of high precision 3D visual landmarks, which improves the landmark matching accuracy dramatically.

2d-3d reasoning and augmented reality publications March 1, 2011

Stable Vision-Aided Navigation for Large-Area Augmented Reality

Han-Pang Chiu, Supun Samarasekera, Rakesh Kumar

In this paper, we present a unified approach for a drift-free and jitter-reduced vision-aided navigation system.

Computer vision publications November 1, 2010

Seamless Indoor/Outdoor 6 DOF Tracking of Trainees and Weapons

Supun Samarasekera, Rakesh Kumar, Han-Pang Chiu

In this paper we present a system for tracking the trainee’s location, head orientation, and weapon orientation that provides high precision and does not require an instrumented site.

2d-3d reasoning and augmented reality publications October 1, 2010

Multi-Modal Sensor Fusion Algorithm for Ubiquitous Infrastructure-Free Localization in Vision-Impaired Environments

Han-Pang Chiu, Supun Samarasekera, Rakesh Kumar

In this paper, we present a unified approach for a camera tracking system based on an error-state Kalman filter algorithm.
